Lexus LS VS Audi A8
- Sumptuous luxury for the price
- Impressive efficiency/performance balance
- Excellent comfort and refinement
- Styling looking a little dated
- Multimedia system too downmarket and also looking dated
- A bit more driver involvement would be terrific
- Unmistakably Audi
- Amazing interior design
- Groundbreaking safety features
- Pricey options
- Most of its autonomous tech locked out for Aus
Lexus is returning to its roots and playing to traditional strengths with the 2021 LS update, as the Japanese luxury brand braces itself for the imminent release of an all-new Mercedes-Benz S-Class.
On sale now from $195,953 before on-road costs, the facelift ushers in a raft of comfort, refinement, driveability and technological upgrades, striving to deliver the quietest and most luxurious experience in the upper luxury sedan segment.
The blink-and-you'll-miss-it makeover runs to redesigned headlights, wheels, bumpers and tail-light lenses, as well as the inevitable multimedia screen update, improved seating revised trim and better safety.
Along with an all-in equipment list and unparalleled levels of ownership benefits, the goal is to emulate the dramatic differences that existed between the LS and its mostly German competition more than 30 years ago, which helped make Lexus a disruptor, decades before the term was even coined.
The MY21 range will continue offering two grades – the racier F Sport and opulent Sports Luxury – in either V6 twin-turbo petrol LS 500 or V6 petrol-electric hybrid LS 500h powertrain choices, as per the XF50-generation's Australian debut back in late 2017.
The question is: has Lexus gone far enough with its limousine flagship?
|Fuel Type||Hybrid with Premium Unleaded|
In a world where genuine wood trim and nappa leather comes in a Mazda6 for under $50,000, premium brands like Audi have been forced to come up with new hallmarks to underpin their status and asking prices.
The new, fourth-generation Audi A8 is no different, packing hardware capable of autonomous driving well ahead of what is currently allowed on any public roads, along with an array of safety, efficiency and convenience firsts for the brand that cement the model's position at the top of the four-ringed luxury tree.
The current S-Class may measure your vital signs and aim to improve your general well-being, but it won't give you a foot massage. If you tick the right options boxes, the new A8 will.
We were among the first to drive the new A8 at its Australian launch around Sydney last week.
|Engine Type||3.0L turbo|
One might be surprised to learn that, without having driven the latest S-Class, rival large luxury sedans have struggled to juggle comfort and refinement with agility and speed. Even in this modern age of adaptive dampers and air suspension. The Germans, in particular, seem to struggle at times.
The latest Lexus LS, however, walks the line with impressive confidence and poise, prioritising the former yet without dropping the ball with the latter. Just keep in mind that the 500h Sports Luxury manages the balance best.
The bar may just about be raised with the bestselling Stuttgart's arrival from March, but even then, with its extensive and complete specification, outstanding hybrid efficiency/performance combination and remarkable build quality and presentation, Japan's master luxury sedan deserves to find more buyers in this country.
Well done, Lexus.
The new A8 is a very accomplished machine, and can certainly be optioned up with enough toys to entertain and comfort whether you're riding in the front or back.
It's not possible to say if its better than the S-Class or 7 Series in isolation, but it has a unique design ambience that's unmistakably Audi. If you're a four-ring devotee, you won't be missing out.
Based on this test, the sweet spot of the range is the long-wheelbase 55 TFSI. At this end of the market, it's fair to say the extra $12,000 for the added length and $3000 for the smoothest and most powerful engine are worth it.
Regardless of the bigger wheels, we'd probably spring for the Premium plus package and the Executive package's rear seat with the Entertainment package for all the most impressive toys. This would mean a total list of almost $250k, but it's arguably how Audi intended the new model to be.
Also check out Peter Anderson's video review from the A8's international launch:
Would you consider the new A8 over an S-Class or 7 Series? Tell us what you think in the comments section below.
The XF50 series is a long and imposing machine, but is also arguably the most Toyota-looking LS in history, sharing design cues with most larger sedans the company builds – and yes, even the Camry. This is a departure from the Mercedes aping ‘90s and '00 generations. If the latest S-Class can look like a 200 per cent enlarged CLA, why not?
The most obvious – and pleasing – changes are realised when the headlights are switched on, revealing the BladeScan tech. In the F Sport, the redesigned bumpers' air intakes are noticeably larger and have jazzier pattern inserts, as part of a broader exercise in differentiating the grades with what's perceived as ‘sportier' elements throughout the car. The divisive ‘Spindle' grille theme remains.
Out back – arguably the most Toyota-esque part of the LS – are piano black tail-light inserts to differentiate new from old.
If Lexus is about presenting nuanced styling evolution as to not spook the demographic, then the MY21 flagship sedan succeeds brilliantly.
At first glance the new A8's exterior styling may look a tad obvious, with unmistakably Audi design adding a bunch of straight lines to make things look more serious.
The reality is far more considered, being the first whole design to emerge under Audi Design boss Marc Lichte's stewardship. Previewed by the first Prologue concept in 2014, the result has an elegance that underlines its position as Audi's flagship and is less likely to be confused with an A6 than the S-Class can be with the E-Class.
If you're after the ultimate in design details and lighting performance, you can also opt for $13,200 laser headlights that can double the range of LED headlights to 600m ahead. This option also brings OLED tail-lights with jewel-like filaments less than 1.0mm thick.
Compared with the third-generation model it replaces, the size of the new A8 is 37mm longer, 13mm taller but 4.0mm narrower, riding on a 6.0mm longer (2998mm) wheelbase. The long wheelbase version is 130mm longer again in wheelbase and overall.
In A8 guise, it combines aluminium, steel, magnesium and CFRP to result in the biggest material variety used in an Audi to date. Kerb weight ranges from 1995kg for the short-wheelbase petrol model to 2020kg for the long-wheelbase version, with the diesel versions adding 55kg respectively.
A 15-spoke, 19-inch wheel design is standard for Australia, but the Premium plus package fitted to all the cars we tested brings a 10-spoke 20-inch design, while the options list includes another three choices of 20-inch wheels. You can also get 21-inch alloys with the optional Sport package.
As you'll see in the interior images, the A8 represents another significant step forward for Audi design, with horizontal themes and numerous traditional controls now hidden beneath touchpads.
Key among these is the deletion of the centre console controller for the multimedia system, which has been replaced by an 8.6-inch secondary touchscreen beneath the 10.1-inch main screen. Apple CarPlay and Android Auto smartphone interfaces are available via USB connection, and the A8 will act as a mobile Wi-Fi hotspot if you sign up for a data plan.
This split layout is less imposing than using one giant screen as in a Tesla, and both give haptic and acoustic feedback to commands to simplify use while driving. All versions also score the excellent 12.3-inch 'Virtual Cockpit' display ahead of the driver.
All A8s also now get a smartphone-like back seat remote controller, which enables control of temperature settings, seat adjustment, lighting, media functions and window blinds (when optioned) via its 5.7-inch OLED touchscreen.
Another surprise detail is that the interior door handles are now power assisted, which represents the lengths Audi has gone to in reducing control weights.
This is more like it.
While nowhere near the apex of striking interior design, with a dashboard that – again – is quite clearly from the contemporary Toyota way of thinking, the LS is massive inside, heaving with standard luxury and obsessively crafted in a few key touchpoint areas.
The brand makes a big noise about the floating door-sited armrests and their very obviously expensive craftspersonship, but it is eye-catching and satisfying to drink in the detailing, extending in and around into the dash seamlessly, carrying on the flowing, salubrious themes of sculptured multi-dimensional shapes. In 1989 journos were handing out similar platitudes in the original LS.
If the techno-overload of a Mercedes MBUX or Tesla's OTT tablet leave you cold, this enhances the luxury experience by adding a rich, cosy, warm ambience – though the instrumentation binnacle is familiar; all we can see is the first IS 250 of 1999, complete with its single, watch-face inspired analogue dial.
Here, of course, it's digitised and multi-configurable to accommodate sat-nav, multimedia and other vehicle-related needs, but it is a oddly nostalgic, given the brand's first BMW 3 Series rival is now almost forgotten. Still, it's interesting and isn't that what eccentric rich people who don't want to drive the cliché luxury behemoths desire?
With endless adjustability, the seats are sumptuous to the point of subsuming, in the way you'd imagine a limousine to be, but because of their bolstered support, they also can be manipulated into gently cupping you enough to stop you sliding about when throwing the Lexus about with gay abandon – more on that later on.
It doesn't need mentioning that the fit and finish is fabulous, with the enveloping luxury continuing out in the back seat. The Sport Luxury's airline-style recliners are enough to turn doubters into doe-eyed believers, with their restful, relaxing, relieving, refreshing and revitalising ways – well, to an extent that an airport massage-chair minus the coin box and dodgy stains can, in any case. But the fact remains: ensconced deep into that leather-lined luxury, slumber beckons. Namaste!
And that's the point of LS. It creates a sanctuary from the outside elements at least as effectively as Audi A8s, BMW 7s and Merc S' have costing upwards of 50 per cent more. The cabin is spacious, soothing and secure. On our extended drive of both 500 models, this was made abundantly clear with two stints behind the wheel of the visually similar ES 300h.
Quiet and refined, that car felt loud and coarse compared to the smooth silence of its supersized sibling. Mission accomplished, Lexus.
Choosing the biggest sedan in the line-up isn't just about outdoing your neighbours, it's also fair to expect enough room to stretch out and ponder your stock options.
Despite the new A8's minor 6.0mm wheelbase growth, the interior dimensions have grown 32mm in length, which has expanded legroom as well as headroom.
Fundamental practicality elements are covered as well, with a cupholder and bottle holder for each outboard passenger, an array of USB and 12-volt charge points and two ISOFIX child seat mounts for the back seat. There's also a Qi wireless phone charger within the centre console.
Boot space is a useful 505 litres, and while there's no split-fold for the back seat, there is the capacity to bring curtain rods home from Bunnings via the ski port. There is also a space saver spare wheel beneath the boot floor.
Price and features
Value, refinement and customer care are Lexus' traditional brand pillars.
Lexus broke through with recession-ravaged consumers at the dawn of the 1990s by firstly presenting an attractively conservative S-Class sized sedan at smaller E-Class prices, and then adding an uncannily hushed cabin of exquisite build quality, silky V8 performance, the entire kitchen sink of gadgetry and unheard-of ownership privileges, like tickets to events, free parking at selected venues and home/work vehicle pick-up at service time.
If such a strategy worked then, why not an expanded version now? After all, while sales started off slowly in Australia three decades ago, in the vital US market its impact was immense. Lexus eventually gained traction locally, but nowadays the LS lags significantly behind the leading S-Class; in 2020, it managed a three per cent share compared to Mercedes' 25.5 per cent – or just 18 registrations versus 163.
Sadly, the V8s haven't returned, but the facelift does bring a richer interior with high-quality materials to elevate comfort levels, backed up by redesigned seating and overhauled adaptive suspension dampers that also promote a cushier ride while not compromising steering/handling performance.
Meanwhile, new ambient lighting and (at last) touch-display capability for the 12.3-inch central screen and Apple CarPlay/Android Auto connectivity do at least play catch up with the rest of the industry, let alone its direct rivals.
The same applies with the fresh safety gains for the series that include a digital rear-view mirror, Lexus Connected Services (with automated collision notification, SOS call and vehicle tracking), Intersection Turning Assist (that helps keep the driver from turning into on-coming traffic or brakes the car if, whilst turning, a pedestrian crosses the road), far-broader functionality of the autonomous emergency braking systems (including greater rear-cross-traffic warning and intervention), full-speed stop/go adaptive cruise control with traffic flow capability, improved road-sign recognition, better lane-keep and assist tech and a next-gen adaptive high beam tech dubbed BladeScan with stronger lighting and anti-glare performance parameters.
These come on top of the standard adaptive dampers, height-adjustable rear air suspension, front/rear cross-traffic alert, sunroof, gesture-activated powered boot lid, soft-close doors, puddle lights, 23-speaker premium audio, digital radio, DVD player, head-up display, satellite navigation, climate control with infrared body temperature sensitivity, heated/vented front and rear outboard seating, powered seats with memory, heated steering wheel, electric rear blind and a four-camera surround-view monitor.
The F Sport from $195,953 differs from the Sport Luxury from $201,078 (both before on-road costs) with its 10 airbags, dark 20-inch alloys and exterior trim hues, brake-package boost, rear-wheel steering, variable gear ratio, unique instrumentation and dark-metallic interior themes and bolstered front seats, while the LS 500 adds active anti-roll bars front and rear.
Going Sports Luxury changes things up somewhat, with two extra airbags (rear-seat cushion items), special noise-reduced alloys, rear-zone climate control, Semi Aniline leather, a front-seat relaxation system, rear-seat tablet-style screens, powered reclinable heated/vented rear seats with ottoman and massage, rear centre armrest with touchscreen climate/multimedia control, side sunshades and – in LS 500 only – a rear cooler box.
On the owner-benefit front, ‘Encore Platinum' introduced last year builds on the regular Encore's valet servicing with benefits like free use of a Lexus for business or leisure travel within select Australian and now-New Zealand destinations (one-way only – sorry, Kiwis) for up to four times annually and lasting the first three years of ownership. There's also eight yearly free valet parking at certain shopping malls and other venues, several celebrity-laden social events/activities and discounted Caltex fuel.
With all these features as standard, the LS costs several tens of thousands of dollars less than most full-sized luxury sedan rivals with broadly similar performance outputs and optioned up with equivalent luxuries, before the Encore Premium privileges. However, while the Lexus' four-year/100,000km warranty also betters most competitors by one year, it is mileage capped while others' regimes aren't, and none beat Mercedes' five-year/unlimited program.
Though prices are up by nearly $2000, it's fair to conclude the extra kit and improvements help offset them, but it's also worth remembering that earlier last year, Lexus hiked LS prices by up to nearly $4000, and not too long before Encore Platinum was announced...
The fact that the new A8's entry price has dropped almost $6000 to $192,000 is likely to have less impact than a $19,990 Hyundai i30 special, but Audi's claim that it offers up to $36,000 more value than before may lower a few bifocals.
Introducing Audi's new naming scheme, which no longer makes reference to engine capacity in preparation for electrification, the diesel base model wears a 50 TDI badge, before moving $3000 north to the petrol 55 TSFI. Either models can be had in long-wheelbase form (signified by a capital L after A8) which will cost you an additional $15,000 respectively.
The $210,000 A8 L 55 TFSI at the top of the price list is more than $42,000 cheaper than the previous V8 diesel 4.2 TDI and a more than $120,000 less than the previous S8 Plus, but a new performance flagship is due to appear in the near future.
Value is rather subjective at this end of the price scale, but by comparison the entry RRP for the new A8 undercuts the base 7 Series by $34,900, the S-Class by $3900, but starts $1871 above the Lexus LS.
Both the A8's 50 and 55 engines come with the same trim levels, but when the standard kit is this lengthy it's more a matter of features not included in the A8, rather than those that are.
As you might expect, there's an array of options available. These accessories range from the aforementioned wheel choices and laser lighting to $3600 Alcantara headlining, $4500 all-wheel steering, a $5200 night vision system, or $12,100 3D Bang & Olufsen sound system with 23 speakers.
There are five options packages also, starting with the $6690 'Entertainment package' which brings a six-disc DVD/CD changer (on top of the standard DVD/CD player) and twin tablets for the rear seats which mount to the front seat headrests.
The nappa leather trim can be expanded to the upper and lower dash and glovebox, door trims, headrests, centre console, steering wheel airbag cover and the backs of the front seats with the 'Full leather package' for an extra $9950.
If you can't hold out for the sport edition S8, you can almost look the part with the $9950 'Sport package', which brings a more aggressive front and rear bumper, 21-inch wheels, all-wheel steering and expanded 'piano black' interior trim.
Audi Australia tells us all A8s ordered to date (along with both cars pictured here) have ticked the $11,000 'Premium plus package', which brings 20-inch rims, adaptive windscreen wipers with integrated jets, chrome exterior details, ambient lighting with variable colours, black control buttons, digital TV, electric rear sunblinds, the full leather package mentioned above, interior fragrancing with ionisation technology, rear tinted windows, softer rear headrests and ventilated massage front seats.
If you've already selected the rear seat entertainment system, you can also choose the $18,500 'Executive package' which brings individual reclining back seats and extended centre console - which also eliminates the centre rear seat - with folding tables, front and rear seat ventilation and massage function, heated armrests all round and a heated steering wheel. It's the Executive package that also brings the heated rear passenger-side footrest and the foot massage USP.
Engine & trans
The LS is powered by two versions of a 3.5-litre V6 petrol engine.
Around 75 per cent of buyers choose the 500, which employs Lexus' V35A-FTS 3445cc double overhead cam 24-valve twin-turbo V6 petrol engine, delivering 310kW of power at 6000rpm and 600Nm of torque from 1600-4800rpm. Powering the rear wheels via an updated AGA0 10-speed torque-converter automatic transmission with driver-adaptive tech, it can reach 100km/h in 5.0 seconds flat, on the way to a 250km/h top speed.
For the facelift, it receives a revised twin-turbo set-up with reduced lag, new pistons and a lighter, one-piece aluminium intake manifold to save weight and cut noise paths while retaining existing outputs.
The 500h, meanwhile, gains software updates for more electrical assistance at lower revs for stronger acceleration times and feel. It employs the 8GR-FXS engine – a 3456cc naturally-aspirated variation with a higher compression ratio (13.0:1 versus the 500's 10.478:1), developing 220kW at 6600rpm and 350Nm at 5100rpm.
Being a series-parallel hybrid, there is a 132kW/300Nm permanent magnet motor and 650-system volt lithium-ion battery, making for a combined power output to 264kW. It now can run longer on pure electric – up to 129km/h compared with 70km/h before. Sending drive to the rear wheels via the L310 continuously variable transmission with a four-speed shift device and a 10-speed simulated shift control operation to mimic more natural auto responses, it requires 5.4s to hit 100km/h, and manages the same top speed as its 500 counterpart.
Both autos, by the way, have more aggressive Sport and Sport+ shift ratio software, while the M manual mode has paddle shifters.
Kerb weight varies from 2215kg (500 Sports Luxury) to 2340kg (500h Sports Luxury).
You might be surprised to learn there's no V8 in the new A8's arsenal - for now, the S8 could change that - but an even greater sign of the times is the return of a petrol version for the first time since 2013. Efficiency gains are the main reason for the petrol comeback, which is explained in detail under the fuel consumption heading below.
Both the 210kW/600Nm 50 TDI turbo-diesel and 250kW/500Nm 55 TFSI petrol specifications use 3.0-litre turbocharged V6s which may seem to be simply plucked from existing models, but they bring mild hybrid technology to the Audi line-up for the first time.
Unlike conventional hybrids that use an electric motor to provide horsepower to drive the vehicle, a mild hybrid (or MHEV) enables the combustion engine to be switched off when the vehicle is coasting or braking, or effectively as an extension of a start/stop system which conserves fuel when a car is stationary.
The A8's mild hybrid system is facilitated by the move to a 48 volt electrical system, with a supplementary 10Ah lithium-ion battery mounted in the boot to keep the electrical systems fed for up to 40 seconds with the engine switched off. Audi claims the system has the capacity to save up to 0.7L/100km.
An extra starter motor has been integrated with the alternator to restart the engine more smoothly via a belt, rather than the conventional cog and ring gear used by the dedicated starter motor for cold starts.
Both engine specs deliver their max torque rating from just above idle, with the 50 TDI at 1250rpm and the 55 TSFI at 1370. Claimed 0-100km/h acceleration performance figures are an impressive 5.9s and 5.6s respectively.
Like all recent longitudinal-engined Audis, the new A8 uses a version of ZF's much lauded eight-speed torque converter auto gearbox, and both engines send power to all four wheels via the 'quattro' all-wheel drive system.
The optional all-wheel steer system can twist the rear wheels by as much as five degrees, reducing the turning circle by around 1.0m at slow speeds. While at higher speeds, the rear wheels move parallel with the fronts by as much as two degrees to improve stability, particularly for rapid lane changes and evasive manoeuvres.
All new A8 variants carry a maximum braked towing capacity of 2300kg.
The LS 500 returns a combined 10.0 litres per 100km, or 14.2L/100km urban and 7.6L/100km extra urban. Thus, the combined carbon dioxide emissions rating is 227 grams per kilometre, but can range from 172-321g/km. A theoretical average range of 820km is possible.
Moving on to the hybrid, the LS 500h manages a combined 6.6L/100km, or 7.8L/100km urban and an impressive 6.2L/100km extra urban. Its combined CO2, therefore, is 150g/km, and can drop as low as 142g/km and rise as high as 180g/km.
The Hybrid's average range should be about 1240km.
Both models require premium unleaded petrol as a minimum - 95 RON in the LS 500 and 98 RON in the Hybrid.
A key goal has been on reducing the stop/start frequency of the 500h's petrol engine during high-speed driving to increase both refinement and response.
Gone are the days where full-size luxury sedans got away with devil-may-care fuel consumption, and even though they still spin six cylinders and need to move around two tonnes, the 55 TFSI petrol versions manage an 8.2L/100km official combined figure. This is when using at least 95 RON Premium unleaded of course.
As you'd expect, the diesel fuel economy is even better with 5.9-6.0 official figures across wheelbases.
With a fuel tank capacity of 72 litres, this suggests a theoretical range between fills of 878km for the petrol models, and between 1200-1220km for the diesels. The A8's spec sheet lists the option of an 82-litre tank if they aren't quite far enough for you.
No matter what it says on the badge, the LS is first and foremost a large, heavy and imposing luxury sedan. Its sporting capabilities are relative.
Keeping that in mind, the updates for the MY21 version are a success, since the largest Lexus passenger car is uncannily quiet and refined, as you might hope and expect. The ride quality is largely cushioned and free of bump intrusion inside, with a sense of gliding over most road surfaces as if they were blemish-free.
We much prefer the Sport Luxury version, and the 500h in particular, because it can run silently in electric mode for periods, and somehow feels more lavish and plusher to ride in.
Whether that's psychosomatic or actual is debatable, for essentially both the 500 and Hybrid share the same multi-link front and rear platform, adaptive dampers and rear air suspension set-up, but the impression is that this grade is the choice for those wanting to feel ultimate luxury and peace.
On paper, the 500 F Sport should be the driver's choice, since it has the racier look and set-up, as well as 600Nm of tree-trunk-pulling torque.
The thing is, it doesn't necessarily feel all that athletic, and maybe that's because the whole existence of this model is based around isolating its occupants as comfortably as possible. This is no criticism, and the LS certainly envelopes everybody as a great limo ought to, but don't expect Audi S8 levels of steering crispness or handling agility.
Anyway, if you need to feel as if you are a princess in exile escaping villains with bazookas out the back of a Kombi, then the LS does an exceptional job in keeping the 2.3-tonne-plus mass in motion, cornering safely and precisely where it is pointed to, without losing too much composure or traction in tight, fast bends. This is quite a feat, really, for the big Lexus can be hurried along a mountain pass through narrow passages like a much smaller sedan, and without being bumped out of line or off course.
Again, for all-out performance, the 500h feels stronger, especially when called on to pull ahead instantly at speed, because the electric assistance is palpable compared to the regular 500's twin-turbo V6. Both are obviously very, very fast and sufficiently responsive to throttle inputs – and it's a sign of the brand's engineering prowess that their internal serenity means the speed isn't obvious until you're looking at the speedo – but there isn't even a whiff of lag in the Hybrid. That said, once on the go, that twin-turbo V6 in the 500 soars.
Considered in this context, you have to say that the MY21 LS is an exceptionally sumptuous and sophisticated limousine with the speed, safety, security and capability of taking you from point A to B without drama or noise.
Or, for that matter, excitement.
Our test started in the worst of Sydney morning traffic, which presented the chance to put the latest adaptive cruise assist (ACA) system through its paces on a very clogged Eastern Distributor.
I'm a huge fan of active cruise control systems that guide the vehicle from speed to a stop, but the A8's ability to start moving again is another step beyond. It helps you avoid being ‘that guy' who hasn't noticed the traffic moving, and would no doubt work wonders for traffic flow if all cars were so equipped. Given the chance, Audi says this system works all the way from 0-250km/h.
No matter what your reaction to the A8's exterior, the freshness of the interior design is like no other, and everything you touch feels first class.
The four-spoke steering wheel has a surprisingly large diameter and is shared with the upcoming A6, but uses thinner spokes than the norm to promote visibility of the virtual cockpit display as the wheel is twirled.
The haptic and acoustic screens make it as easy as we've experienced to handle a touchscreen while driving, but not quite as simple as the previous console controller.
Front and rear seats are softly padded for comfort rather than support, and unsurprisingly there's ample room in every direction for this 172cm tester, regardless of wheelbase.
All examples of the A8 we drove were optioned with the Premium plus package, which means one inch larger 20-inch alloys. Despite all A8s coming standard with adaptive air suspension, small bumps like cats eyes and expansion joints are more noticeable than you might expect. As is often the case, the standard 19-inch alloy wheels are likely to be the solution.
We drove both engines and wheelbase choices at the A8 launch event, and you need to be paying close attention to hear any extra noise from the diesel. It does make a muted groan under throttle, but likely worth the 300-plus kilometres of extra range if that's what you're after.
The diesel's smoothness is also no doubt aided by its use of active engine mounts. If you're after outright refinement and performance, the petrol is the one for you but neither feel in any way sluggish.
Heading through the bends of the Royal National Park and then back over the hills via Macquarie Pass at pace, there was no disguising the fact that the A8 is a big car, and it tends to float unless you select 'Dynamic' from the drive mode selector. Regardless of mode, it's more planted than any luxury SUV.
Making a bee-line back to Sydney via the Hume, the A8 simply wafted along at 110km/h in near silence. As you'd expect.
Neither the ANCAP organisation nor Euro NCAP has crash-tested an LS for this or previous generations. And, for that matter, nor has the American NHTSA or IIHS, due to low sales.
Standard safety items include 10 to 12 airbags (depending on model, with dual front, front-side and curtain items), AEB with pedestrian and cyclist detection, forward collision warning, driver attention alert, Lane Keep Assist, a Front Lateral Side Pre-Collision System, Active Steering Assist, radar-based adaptive cruise control, Parking Support Brake, Road Sign Assist (detects certain speed signs), a four-camera Panoramic View Monitor, Blind Spot Monitor, Lexus Connected Services, Electronic Stability Control, traction control, anti-lock brakes with electronic brake-force distribution and brake-assist, and parking sensors all-round. The BladeScan adaptive LED headlights with anti-dazzle tech is also fitted.
The LS' AEB functions between 5km/h and 180km/h.
Additionally, two rear-seat ISOFIX points as well as three top tethers for straps are supplied.
The airbag count has been further bolstered by an industry-first centre airbag, which has been designed to prevent head clashes between front seat occupants. This also represents Audi thinking beyond any Euro NCAP or ANCAP criteria.
It also comes with Audi's exit warning system, which warns the driver of passing cars or cyclists but can now delay the door opening in case the driver doesn't see the warning light.
A front-mounted laser scanner replaces the usual radar system for active cruise control and front AEB, which doubles the range of a radar scanner to 80m and enables both functions to work at speeds up to 250km/h.
This laser scanner is also key to the A8's Level 3 autonomous preparation, but local laws limit its capability to active cruise control with lane assist.
Lexus offers a four-year 100,000km warranty, which is considered one of the worst in the industry for mileage distance, due to the low number. Most rivals offer unlimited kilometre warranties, as well as more years in some cases.
However, it does come with a three-year program covering standard logbook services completed at an authorised service centre, with the first three annual/15,000km services for the LS costing $595 apiece.
A complimentary pickup and return service from home or workplace is available, as are a loan car, exterior wash and an interior vacuum during servicing. It's all part of the Lexus Encore Owners Benefit program, offered for three years and includes 24/7 roadside assistance.
Finally, the Encore Platinum brings the aforementioned travel destination free Lexus vehicle program (four times a year over three years) in Australia and NZ, as well as numerous valet parking and events privileges, limited to a several annually, and discounted fuel at participating outlets.
Like all Audis, the new A8 is covered by a three year, unlimited kilometre warranty. This is short of the five year-plus periods becoming more common among mainstream brands, but equal to the terms offered by BMW and Mercedes-Benz. Lexus differs by offering a four year, 100,000km plan.
Service intervals and capped price servicing mirror the previous A8, with a 12 month/15,000km schedule, and maintenance costs for the first three services can be wrapped into a package for $1900.
We had no issues during our test, but any common faults, common problems or reliability issues are likely to appear on our A8 problems page.
